Soda-water apparatus

SODA-WATER APPARATUS.

Specification of Letters Patent No. 32,709, dated July 2, 1861.

,'lo all whom it may concern:

Be it known that I, Farmers NICHOLS, of New London, in the county of New London and State of Connecticut, have invented a. new and useful Improvement in Soda-later Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, said drawing representing a vertical section of a soda-water counter, with such parts of the apparatus as are necessary to illustrate my invention.

My invention consists in so combining the casing of the draft-tube with the cooler by means of suitable pipes, that said casing is made to constitute a portion of a siphon through which the waste ice-water from the cooler is caused to circulate, for the purpose of keeping the draft-tube cool. It also consists in so constructing a casing surrounding the syrup vessels and so combining` the same with the cooler b means of pipes as to make the said casing form a portion of a siphon by which the icewater is caused to be drawn from the cooler, the latter siphon being the same by which the ice-water is drawn through the casing' of the draft-tube or a separate one.

To enable others to make and use my invention, I will proceed to describe its construction and operation. A

The drawing represents the casing of the draft-pipe and the asing of the syrup vessels as parts of the same siphon.

A, is the counter; B, the casing of the draft-tube, erected upon the counter in the usual manner. y'

The cooler, C, arranged under the counter; the pipe, l), from the fountain, taking the form of a coil within the cooler; and the pipe, E, leading from the coil up to the draft-tube, F, are all represented in red outline to distinguish them from the parts to which my invention more particularly relates.

G, is an india-rubber or other pipe connected by a nozzle, a, passing through the top of the counter, with the bottom of the casing B, and entering the cooler C; such pipe combining with the casing B, to form the shorter leg of the siphon.

II, is a metal pipe secured in the bottom of the casing B, extending upward therein nearly to the top of the said casing and projecting through the bottom thereof te form a nozzle, b, to pass through the counter for the attachment of an india-rubber pipe, I, below the counter, the latter pipe being connected with a nozzle on the casing, J, of the syrup vessels, which is arranged on a suitable shelf or support below the counter. This .casing J, consists of an air-tight box of tin plate or other metal, containing any number of syrup vessels, c, c, according to the number ot' different kinds of syrup desired; such vessels being soldered or otherwise secured in an air-tight manner .in openings in the top of the said box, and consequently being entirely immersed in or surrounded by water when the said boX is full.

L, is a waste-pipe, connecting with the bottom of the casing J.

The pipes I and H, the casing J, and the pipe L, constitute the longer leg of the siphon, care being taken that the mouth of the tube L is lower than the mouth of G. The pipe I, may be provided with a cock to regulate the flow of water in the siphon. The siphon may be filled to start its operation, by closing the ends of the pipes G and L, or raising them above the top of the draft-tube casing B, taking off the cap, cl, of the said casing, and pouring in water atthe top of the said casing; removing also a plug, p, in the top of the casing of the syrup vessels until the said casing is full.

lVhen the cooler C is supplied with ice and the siphon is in operation, the waste water resulting from the melting of the ice collects atfthe bottom of the cooler and is caused to ow up the pipe G, through the casing B, around the draft tube down the pipes H and I, through the casing J, and around the syrup vessels escaping by the pipe L, cooling in its passage both the drafttube and the syrup vessels. The escape by the pipe L, should however be so regulated that it does not carry ott' the water faster than it collects in the cooler C, or the action of the siphon will be stopped by the entrance of air. By this mode of carrying otl' the waste water, which leaves the cooler atv a temperature ot' about 32 Fah., much ice is saved, as the water is usually thrown away directly from the cooler; and besides this saving of ice, the necessity for the use of any ice above the counter, for filling casing B, or coolino syrups, is obviated.

I employ 'or drawing the syrups from the Vessels c, c, any of the well known elastic syringes, as these can be very conveniently rounds the syrup vessels, with the cooler C,- by means of a system of pipes by Which the said casing is made to form a portion of a siphon substantially as herein specified.

3. Combining the casings'B and J, With each other, and with the cooler C, by a system of pipes which make both of said casings constitute portions of the same siphon, substantially as and for the purpose herein specified. FRANCIS NICHOLS. fitnesses S. IV. JONES, S. I. STARR.
